Increasing the humidity in your home is key to keeping your houseplants healthy and thriving during the cold, dry months.

Read the Grow-How™ Team‘s favorite ways to increase the humidity to keep houseplants healthy throughout the year.

Many of our indoor plants originate from humid jungle environments, so moisture in the air is vital to keep plants lush and healthy. The ideal humidity for houseplants is 40-60% higher than the humidity levels found in our homes, especially during the winter when fireplaces and furnaces create drier air conditions. To provide your plants with an ideal living environment in the winter, it’s essential to increase the humidity for your plants.

In addition to misting your plants regularly, there are several options to keep your plants (and yourself!) healthy and happy during the drier winter months.

What are the signs that your plants need higher humidity?

Your plant has many ways of telling you that it needs more humidity. A few signs are:

  • Leaves begin to develop brown edges
  • Plants begin to wilt and droop
  • Leaves begin to turn yellow
  • Foliage becomes crispy to touch

If any of your plants are exhibiting any of the symptoms listed above, lack of humidity may be the culprit.

How to increase the humidity for your plants

Mist your plants

This will raise the humidity around the plant, but the effect is temporary. Never mist plants with hairy leaves, such as African violets, Purple Heart, Stretocarpella to name a few. The “hair” on the leaves holds water in place, encouraging diseases and leaving spots on the foliage.

Use pebble trays

Place a layer of pebbles in the tray, add water until the pebbles are not quite covered, and set the plants on top. The pebbles hold the plant above the water so that the roots are not constantly wet. As the water in the tray evaporates, it increases the moisture in the air around the plant.

Create a microclimate

Place several plants in a group, creating a pocket of humidity. If able to, put a dish of water or a small watering can full of water in the center.

Use a humidifier

Good for the plants but also good for humans to add extra humidity during the winter period.

Give them a bath

Give your plants regular showers or baths during the winter months. Not only do they enjoy the extra moisture, but this will also clean any dust from the foliage where tiny pests like to hide. Remember to use lukewarm water.
